Electric Vehicle: Components, Charging Infrastructure and Grid Integration Solutions | Effect of EV Charging Stations on Grid – II | Voltage Drop, Power Quality & Transformer Impacts | Lecture 42

This lecture discusses the electrical and technical impacts of EV charging stations on distribution networks, including voltage drop, feeder overloading, power losses, phase unbalance, and voltage flicker.
The lecture also covers power-quality issues caused by power-electronic chargers, such as harmonic distortion, transformer heating, neutral overloading, and power-factor degradation. The role of controlled charging in reducing voltage problems and improving grid performance is also highlighted.
